CLARANCE WILLIAMS, OF MERRILLVILLE, CALIFORNIA.

, WRENCH.

Application filed June 8,1915.

To all whom it may concern:

Be it known that I, CLARANCE A. WIL- LIAMS, a citizen of the United States, residing at Merrillville, in the county of Lassen and State of California, have invented a new and useful Wrench; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved wrench, and an object of the invention is to provide a wrench which is simple, efiicient and practical in construction, and the shank handles of the jaws are so made, as to enable the operator to secure along leverage, upon that which is to be turned, and without allowing the jaws to become loose or separated.

Another object of the invention is to provide an improved wrench, so constructed, as to enable the operator to secure slight adjustment of the jaws, and at the same time to permit substantially a three-cornered grapple and bracing effect in wrenching that which is to be turned.

One of the features of the invention is the provision of two jaws, one of which is lon gitudinally channeled, for the reception of the other jaw, the sides of the channeled jaw having angularly disposed registering slots, through which the guide pin which is rectangular in cross section extends, the guide pin being carried by the jaw which is adjustable in the channel. The gripping faces of the jaws extend at an obtuse angle to the length of the shank handles, and at right 7 angles to the slots, thereby permitting the jaws to be inserted in inconvenient places, and yet permit a long leverage and considerable movement of the handle of the wrench.

This particular type of wrench is more especially adapted forlaving railway tracks and the like. in view of the fact that the jaws are enabled to reach up under the nuts in applying fish plates so thatthe wrench may be given a half turn.

In practical fields the details of construc- .tion may necessitate alterations, falling wi hin'the scope of what is claimed.

The invention comprises ,further features and combination of parts, as hereinafter set forth, shown in thedrawings and claimed.

In the drawings: Figure 1 is a view in.

side of a rail, whereby substantially a full half turn may be imparted to the nut. Fig. 2 is a perspective view. Fig. 3 is a sectional view longitudinally, showing parts in elevation.

Referring more especially to the drawings, l designates the jaws of the wrench. The jaw 1 is enlarged and substantially diamond shaped and provided with the lug 3, which constitutes the gripping aw proper. This diamond-shaped enlarged portion of the jaw 1 is longitudinally channeled as shown at 4, which channel 1 extends entirely through the jaw 1 as shown at 7 The opposing sides of the jaw 1, between which sides the channel is formed, are provided with angularly extending registering slots 8. The jaw 2 is provided with an enlargement 9, which is adjustable in the channel, and the tongueportion 10 of this enlargement 9 extends through that portion of the channel which extends entirely through the aw 1. Removably fixed in a square aperture of said tongue is a correspondingly constructed pin 11, the opposite ends of which engage the registering slots 8, thereby guiding the jaw 1 during its various adjustments.

In practice the ends of the rectangular pin 11 have sufficient play in the slots 8, to permit the pin to slide, and this play is sufficient to permit the jaw member having the tongue to rock just enough to permit the tooth 20 of the shank 22 to move out of'engagement with the ratchet teeth19, so that the jaw members may be adjusted. Forming an integral part of the jaw 2 is a lug 14, which constitutes the other gripping jaw proper for cooperation with the jaw 3. The shoulders 15 of the jaw proper let engage the edge portion 16 of the jaw 1. The

shank handle 17 at its extremity is constructed with a socket housing 18, and its inner wall 18 is provided with ratchet teeth 19, to be engaged. by the tooth 20 at the extremity 21 of the handle shank 22 of the jaw 2, so as to prevent movement of the jaw 2 in the direction of the socket housing. A suitable spring 23 is bent or constructed as shown at 21. so as to engage the transverse pins or lugs 25 of the socket h0using, for holding the spring in position. The

"free portion 26 of this spring engages the .edge27 of the shank handle of the jaw 2,

in order to hold the tooth 20 in engagement with any two of the teeth 19 of the socket teeth 19, and in moving the tooth out of engagement with the teeth 19, the pin 11 rocks but a trifle in the slots 8. In practice the teeth 19 will be constructed considerably smaller and in greater numbers, for the showing of the teeth 19 in the drawing is exaggerated for the mere purpose of illustration, and in case the play of the pin 11 in the slot 8 is not suflicient, the extreme portion of the shank 22 may be sprung sufficiently to permit the tooth 20 to be disengaged from the teeth 19.

' The invention having been set forth, what is claimed as new and useful is r 1. A wrench comprising a pair of jaw members, one of them being providedwith an enlargement and having a channel extending longitudinallv thereof and entirely through-the jaw, said channel in cross section being elongated, the other jaw member having an enlargement of a shape transversely corresponding to the contour of the channeltransversely and fitting the channel, and "having a tongue extending through that portion of the channel which extends through the first jaw, the opposite sides of the channel jaw member being provided with elongated registering slots extending angularly and in a direction toward the shanks of the jaw members, means carried bvthe tongue and guided in said slots, said jaw members having opposing cooperating aws proper extending at obtuse angles to the jaw members and at right angles to the slots, one of the jaw members terminating in a shank handle havlng a socket housing, the

other jaw member having a shank handle engaging the socket housing. and means in the socket housing for holding the jaw members in adjusted positions.

2. A wrench comprising a pair of jaw members, one of them being provided with an enlargement and having a channel extending longitudinallv thereof and entirely through the jaw, said channel in cross section being elongated, the other jaw member having an enlargement of a shape transverselv corresponding to the contour of the channel transversely and fitting the channel, and having a tongue extending through that portion of the channel which extends through the first jaw, the opposite sides of the channel jaw member being provided with elongated registering slots extending angularly and in a direction toward the shanks of the jaw members, a pin extending transversely of the tongue and being guided in said slots, said jaw members having opposing cooperating jaws proper extending at obtuse angles with the jaw members and at right angles to the slots, said jaw members having shank handles, one of the shank handles having a socket housing provided with teeth upon one of its interior surfaces, the other shank handle having a tooth at its extremity to engage any one of said teeth to prevent movement of the jaw member adjustable in the channel, and a spring fixed in the socket housing to hold said tooth in engagement with said teeth.

3. A wrench comprising a pair of jaw members, one of which is provided with an enlargement having a channel extending angularly and entirely through the enlargement, said channel in cross section being elongated, the other jaw member having an enlargement of a shape corresponding to the contour of the channel transversely and.

fitting the channel, and having a tongue extending through that portion of the channel which extends through the first jaw, the

"opposite sides of the channel jaw member being provided with elongated registering slots extending angularly in a direction toward the shanks of the jaw members and substantially corresponding to the disposition of the channel, apin rectangular in cross section and carried by the tongue and guided in said slots, said jaw members having opposing cooperating jaws proper extending at obtuse angles to the jaw members and at right angles to the slot, the sides of the channel jaw member having guiding shoulders, the jaw member having the tongue being provided with guiding shoulders adjacent the jaw proper to cooperate with the first guiding shoulders, the jaw members terminating in shank handles one having a socket housing to receive the other and provided with means for holding the aw members in adjusted positions.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
